Abstract

L'invention concerne un procédé pour améliorer l'alimentation en courant de cuves d'électrolyse alignées en long, permettant de réduire l'influence nocive des champs magnétiques enduits. Dans une série, chaque cuve est alimentée en courant, à partir de la cuve précédente, à la fois par la tête et par au moins une montée latérale. Les barres de sorties cathodiques sont divisées en deux groupes indépendants, le groupe amont alimentant la tête de la cuve suivante, et le groupe aval alimentant les montées latérales de la cuve suivante. Il en résulte une amélioration sensible du rendement et une plus grande régularité de marche. Application aux séries de cuves pour la production d'aluminium par électrolyse ignée de l'alumine dissoute dans la cryolithe.The invention relates to a method for improving the current supply of electrolytic cells aligned along the length, thereby reducing the harmful influence of coated magnetic fields. In a series, each tank is supplied with current, from the previous tank, both by the head and by at least one side rise. The cathode output bars are divided into two independent groups, the upstream group supplying the head of the next tank, and the downstream group supplying the side risers of the next tank. This results in a significant improvement in performance and greater regularity of walking. Application to series of tanks for the production of aluminum by igneous electrolysis of alumina dissolved in cryolite.
